ipv6: Return error for RTA_VIA attribute
IPv6 currently does not support nexthops outside of the AF_INET6 family. Specifically, it does not handle RTA_VIA attribute. If it is passed in a route add request, the actual route added only uses the device which is clearly not what the user intended: $ ip -6 ro add 2001:db8:2::/64 via inet 172.16.1.1 dev eth0 $ ip ro ls ... 2001:db8:2::/64 dev eth0 metric 1024 pref medium Catch this and fail the route add: $ ip -6 ro add 2001:db8:2::/64 via inet 172.16.1.1 dev eth0 Error: IPv6 does not support RTA_VIA attribute.
